BOILER MAGAZINE FRONT.

Application filed February 21, 1921. Serial No. 446,882.

To all whom it may concern:

Be it known that I, CHARLES C. FULGHUM,

a citizen of the United States, residing in the city of Richmond, in the county of W ayne and State of Indiana, have invented a new and useful Boiler Magazine Front, of which the followlng 1s a full, clear, and accurate specificatlon, thesame being such as will enable others who are familiar with the forming the front of the magazine but 10- cated back from the furnace front.

My object in this instance is to provide such a partition, with means whereby it may be adjusted to adapt the magazine to va-'.

a maximum of circulation in order that it will absorb a maximum amount of heat in its passage therethrough, in order that said heat may later be available for radiation through the regular means installed for that purpose.

Another object is to provide means for the passage of air over. theupper edge of the device in order that the fuel gases may be utilized. And also to provide means for adjusting the device from the outside, that is without opening the furnace.

vAnother feature of this invention is the provision of slots or flues through the lower portion of the device whereby I am enabled to admit air above the lower edge of the device which is especially desirable when ash or refuse has accumulated on. the grates to such an extent that passage of air therethrough is retarded.

Other objects and particular advantages of the invention will be suggestedfin the course of the following exposition.

One manner of carrying out the principles of this invention in an efficient and practlcal manner is shown in the accompanying draw ings, in whichFigure 1 is a perspective view of my partition or .front, certain portions being broken away in order to exhibit the interior of the. device. Figure 2 is a vertical central section of my device; as taken on the line 22--of Fig. 1. Figure 3 is an end elevation of'my invention. Figure 4: shows an end elevation of my device as 10- with a furnace, showing the invention, on a .reduced scale from that of the otherviews.

Figure 5 is a front elevation of a modified construction, partly broken away inflorder 'to. show the interior arrangement thereof.

Similar indices denote like parts throughout the several Views. I

As it is desirable that the invention should be fully understood in. order to v be ..appreciated, therefore I will now' take'up a detailed description thereof.

In the drawings letter A denotes thefront or shell of a furnace, and B. denotes, the sloping top, whichphas a fueldoor Gtherein. D denotes the grates and E denotes the ash pit. LetterFdenotes the backgofthe fuel magazine below which are the louvres G from-between, which the heat passes through into the boilerproper, which latter is not shown inthis instance, but itappears in a companion application.

The invention proper consistsof the partition which'is, shown in Fig. 1,,and it comprises the front 1, the back 2, the. ends '3 and l, thebottom 5, andthe top 6, all of said parts being integral witheach-other, with thelower portion of-the device, directed at an anglewith relation to themajor upper portion, the direction of inclination changing at the. point marked 00 in the drawings.

Formed integral with andextending upward from the back 2 and from the top 6, is the flange 7 whose thickness is. substantially equal to the combined thickness'of the back 2 and the top 6, and the ends of the flange 7 are braced to the top 6: andtheends 3 and 4, by'the respective brackets or fin 8 and 9.

The upper corners of the flange 7 terthe flange? and the;underside of the-top B, as shown.

A pluralityof flues 12 are formed through the lower portion of the device,.: andl-they cated in operative position in connection open through both the front 1 and the back 2, substantially as shown in the drawings.

Numerals 13 and 14 denote, respectively, the intake and outlet pipes, and they form the pivots by which the device is suspended.

Located a. short distance inward from the end 3 and parallel therewith is the baffle plate 15, the same being connected with the front 1 and the back 2 between which it extends, and it projects from the top 6 to within a. short distance of the angle 00, as shown in Fig. 1. A very small aperture 2 is formed through the plate 15 at a point approximate the intake 13.

As intimated, the pipes 13 and 1e act as pivots, by which the device is suspended, the outer ends of the pipes 13 and 14: being rotatably mounted in suitable couplings not shown in this instance.

The means for manually adjusting the device comprises the following: Formed integral with the central portion of the face of the front 1 is a boss 16 which is interiorly threaded to receive the threaded end of the member 17 of the shaft or arm. The outer end of the member 17 is flattened to correspond with the flattened rear end of the member 18 of said arm. The flattened portions of the members 17 and 18 being pivotedly connected together by the bolt 19. The member 18 is made hollow, and on its forward end is secured the cap-nut 20 through which is threaded the stem 21. Formed on the face of the front A is a lug 22, there being a smooth aperture formed through the lug 22 and the front A in which may freely revolve the stem 21. Collars 23 and 2 1 are secured around the stem 21, the former contacting with the inner face of the front A, and the latter with the lug 22. The outer end 25 of. the stem 21 is pro vided with means to receive a crank or other tool by which the stem may be rotated.

As indicated in Fig. 5 the vertical baflie 15 may be dispensed with and the diagonally disposed baflie 26 substituted therefor. However the results will be practically the same in each instance.

Operation: In practice the device is to be employed in connection with a furnace or boiler which is arranged substantially as shown in Fig. 1. The magazine is to be supplied with fuel, as shown, which may be entered through the door C, combustion being maintained at or near the grate-bars D, and the combustion may extend up as far as the upper louvre G, the draft being drawn to the chimney from between the louvres as indicated by the arrows.

By turning the stem 21 it is manifest that my device may be adjusted forward or rearward, depending on the kind of fuel used, thereby providing means whereby any kind of fuel coal from slack to lump may be employed with substantially equal success.

As combustion continues it is evident that the coal in the fuel magazine will become heated and will throw off more or less gas or smoke, especially from that nearest the combustion zone. The gas mentioned usually passes up the chimney without being consumed, or it might rise into the upper portion of magazine and escape, especially when the door 0 is opened, but by reason of the slot y it is evident that air from the outside, for instance from the ash pit, may pass up in front of the device and back of the front A, whereby the suction from the flue will permit the gas from the magazine to be drawn down into the combustion zone through the incandescent body of fire and thereby consumed, by which I obtain the maximum of heat from the fuel, but this can only be accomplished by the provision of the slot y which permits fresh air to take the place of the gas consumed, all of which I have found by actual observations.

In the construction set forth it is essential that the device have a circulation of Water therein to protect the partition or front from damage by heat; and also the circulation therethrough causes the water to absorb heat which would otherwise be lost.

The water enters the device through the pipe 13. It first comes into contact with the baflie 15 whereby the water is caused to pass downward into the lower portion of the device, passing around the flues 12, and finally rising and passing out through the pipe 4, all of which is indicated by the arrows in Fig. 1.

I desire that it be understood that various changes may be made in the several details of construction without departing from the spirit of the invention nd without sacrificing any of the advantages thereof which are new and useful.

Having now fully shown and described my invention, what I claim and desire to secure by Letters Patent of the United States, is

1. A boiler magazine front comprising a flat container, an inlet near the top and at one side of the device, an outlet opposite to said inlet, means for causing the circulation to pass downward from the inlet and then upward to the outlet, a flange extending the full length of and upward from the upper edge of the container, means for preventing the upper edge of the flange from'contacting an element located thereabove, and flues extending through the lower portion of the container, substantially as set forth.

2. A magazine front for heating plants comprising a flat container, the lower portion of the container being disposed at an obtuse angle with relation to the upper portion, flues forming passage-ways through the lower portion of the container, a single flange extending up from the upper edge of the container, an upwardly extending point at each end of the flange, an inlet pipe at the upper portion of the container, an outlet pipe opposite said inlet, a battle dividing the interior of the container between the inlet and the outlet, and means for adjusting the position of the container from a point outside the furnace.

3. A magazine partition for boilers comprising a movable device including a front and a back spaced apart and having ends, a bottom, and a top all formed integral with each other, the minor lower portion of the device being directed at an obtuse angle with relation to the upper or major portion, a flange extending upward from the back and the top, fins for bracing the flange from the top, points extending up from each end of the flange, a plurality of fiues formed through the lower minor portion of the device and opening through both the front and the back, intake and outlet pipes extending out horizontally from the upper portion of the device and forming pivots on which the device may swing forward and rearward, a baffle plate connecting the front and the back and located between the intake and the outlet and extending from the top to near said flues and having a small aperture therethrough opposite to the intake pipe, and means whereby the device may be swung forward and backward by a person located at a distance therefrom, all substantially as shown and described. I

In testimony whereof I have hereunto subscribed my name to this specification in the presence of two subscribing witnesses.
